SYMPTOMS
========

When you are using a DCA IRMAtrac Convertible Token Ring network adapter in ISA
mode, you may receive the following error message when you use the NET START
command:

  Invalid entry for DMAChannel in PROTOCOL.INI

This problem occurs only if you are loading real-mode (NDIS 2) drivers for the
network adapter.

CAUSE
=====

The network adapter is configured to use DMA channel 3 or 7. Windows 95 does not
support the use of DMA channel 3 or 7 with the DCA IRMAtrac Convertible Token
Ring network adapter.

RESOLUTION
==========

Configure the network adapter to use DMA channel 5 or 6 in ISA mode. To do so,
follow these steps:

1. Use the right mouse button to click My Computer, then click Properties on the
  menu that appears.

2. Click the Device Manager tab.

3. Click the DCA network adapter, then click Properties. Note that you may have
  to expand a branch of the hardware tree by double-clicking the branch, or
  clicking the plus sign (+) to the left of the branch, before you can click
  the network adapter.

4. Click the Resources tab.

5. Click Direct Memory Access, then click Change Setting.

6. Type the DMA channel you want to use, then click OK.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Windows 95. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
